promoter methylation status and protein expression of brca2 in patients with epithelial ovarian cancer
Authors
abstract
background : ovarian cancer is the leading cause of death among gynecological cancers. changes in the methylation of brca1 and brca2 may be an effective mechanism for breast and ovarian cancer. this study evaluates the protein expression and methylation status of brca2 in iranian patients. methods : we assessed 60 mullerian-type ovarian cancers by methylation-specific pcr assays and immunohistochemistry. results : according to methylation status analysis, there were 7 of 60 (11.66%) methylated cases that had low protein expression. conclusion : we concluded that changes in the methylation status of brca2 cannot be used as an appropriate biomarker to ascertain the development of ovarian cancer.

PCSK9 Associated Promoter Methylation Status in Patients with Hyperlipidemia
Background and purpose: Hyperlipidemia is one of the main risk factors for coronary artery disease and is defined as abnormal elevation of lipids or lipoproteins in the blood. Pcsk9 is the ninth member of the proprotein convertase family that binds to the LDLR on the surface of the hepatocyte, leading to degradation of LDLR in lysosomes which could cause hyperlipidemia. The present study aimed...

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولMethylation status and immunohistochemistry of BRCA1 in epithelial ovarian cancer.
BACKGROUND Cancer initiation and progression are controlled by genetic and epigenetic events. One epigenetic process which is widely known is DNA methylation, a cause of gene silencing. If a gene is silenced the protein which it encodes will not expressed. OBJECTIVES 1. Identify the methylation status of BRCA1 in patients with epithelial ovarian cancer (EOC)and assess BRCA1 protein expression...
full textSHOX2 and WT1 Promoter Methylation Correlates with the Lung Cancer in Iranian Patients
Lung cancer is among the most common cause of cancer death in the world. Since the disease is diagnosed in the middle or late stages of the cancer development a more efficient method for an early diagnosis of the disease is required. The main goal of this study was to investigate the correlation between aberrant promoter methylation of the two genes: SHOX2(Short stature homeobox 2) and WT1(Wilm...
full textPRAME expression and promoter hypomethylation in epithelial ovarian cancer
PRAME is a cancer-testis antigen (CTA) and potential immuno-therapeutic target, but has not been well-studied in epithelial ovarian cancer (EOC) or its high grade serous (HGSC) subtype. Compared to normal ovary, PRAME expression was significantly increased most EOC, regardless of stage and grade. Interestingly, PRAME mRNA expression was associated with improved survival in the HGSC subtype. The...
